<h3><a name="intro"></a>Values and Threshholds</h3>

<p>If a device supports the <i>Self-Monitoring, Analysis and Reporting Technology</i> (S.M.A.R.T.)
it offers readable access to the attribute table. There you find the <tt>Raw Value</tt>,
a <tt>Normalised Value</tt> and a <tt>Threshhold</tt> (set by the vendor) for each attribute,
supported by that device.</p>

<p class="marked">What about Field "Worst"? I didn't find it
mentioned here:
<a href="http://www.t13.org/Documents/UploadedDocuments/docs2005/e05148r0-ACS-SMARTAttributesAnnex.pdf">http://www.t13.org/Documents/UploadedDocuments/docs2005/e05148r0-ACS-SMARTAttributesAnnex.pdf</a></p>

<p>The meaning and handling of the <tt>Raw Value</tt> is a <i>secret</i> of the vendors
embedded S.M.A.R.T.-Software on the disk. The only relevant info from our external view
is the <tt>Normalised Value</tt> in comparison with the <tt>Threshhold</tt>.
If the attribute value is greater than or equal to the threshhold, the attribute signals
its failure and the <tt>Health Status</tt> of the device will switch from <tt>Passed</tt> to
<tt>Failed</tt>. Depending on your systems configuration, you will get a warning.</p>
